Enigmatic Channels on the Floor of Mangala Valles

This particular area, called Mangala Valles and located near the Tharsis region, may be an example of the action of liquid water in the ancient Martian past.

It’s possible that the wide and short channels visible here may have formed by the motion of groundwater, similar to way channels like these form on Earth.
